We usually use the Landolt Ring method for testing visual acuity. But it is difficult to test visual acuity of severely handicapped children, since they must say about the direction of some rings in the method. A new method which we have been developing doesn't have necessity of saying. On this method,the eyes are judged visual acuity from the pictures or video camera works of them. When the storobe flashes on the eyes in the dark,this device records the eyes on films or video tapes. Then we can find the anomalies of refraction from them. We examined 374people by this method. The result of this correlated closely with he result of Auto Refractomater (correlation coefficcent ; 0.889). And we tried to examine 150 andicapped children, and succeeded to test 148 children.

我们通常使用Landolt环法来测试视力。但是，由于在该方法中必须说明某些环的方向，因此很难测试严重残疾儿童的视力。我们正在研究的一种新方法是没有必要说的。该方法是根据眼睛的照片或摄像作品来判断眼睛的视力。当storobe在黑暗中对着眼睛闪烁时，这个设备就会把眼睛记录在胶片或录像带上。然后我们就可以从中找出折射的异常。我们用这种方法检查了374人。结果与自动验光仪测定结果有较好的相关性（r = 0.889）。对150名残疾儿童进行了测试，成功测试了148名残疾儿童.
